ANS ALERT: Monitoring finds Evidence of Quagga Mussel Larvae in Green Mountain Reservoir
On Aug. 18, as part of a state and federal initiative to monitor aquatic nuisance species (ANS) in the state, specialists with the U.S. Bureau of Reclamation first confirmed the presence of the veligers, initially through microscopic analysis followed by DNA testing. An independent laboratory contracted by Colorado Parks and Wildlife confirmed Reclamation's findings. It is unknown if the veligers were dead or alive at the time of detection. For more information, please see the press release.
What does this mean for boaters?
Boats entering Green Mountain Reservoir will continue to inspected prior to entry to prevent further introductions of mussels into the reservoir.
Boats at Green Mountain Reservoir will now receive a high risk inspection after coming off the water. If the boat has ballast tanks, an inboard or an inboard/outboard engine, or can not be fully drained and dried, they will be required to get decontaminated.All boats leaving will get a green seal and blue receipt indicating they were last in Green Mountain Reservoir and have followed proper inspection and decontamination procedures. (White receipts are used at negative waters.) For more information, please see the Boater’s Guide to Aquatic Nuisance Species (ANS) Inspections.
Green Mountain seals and receipts (blue or white) are no longer valid for pre-inspection anywhere in Colorado State Parks.
Following the Labor Day weekend, boats will be required to enter and exit the reservoir from the Heeney Marina ramp.
